> When a request is made directly to a JSP (not via a page flow) and the rendering of the
JSP throws an exception, the PageFlowPageFilter will catch the exception and try to use the
DefaultExceptionsHandler. However, the DefaultExceptionsHandler expects the request to be
a PageFlowRequestWrapper and calls PageFlowRequestWrapper.get(). In this scenario, the request
is not a PageFlowRequestWrapper so the get() method throws either an AssertException (when
checking for the PageFlowRequestWrapper) or a ClassCastException when running without asserts.
> Here's an example stack trace...
> java.lang.ClassCastException: org.apache.coyote.tomcat5.CoyoteRequestFacade
